The HumPRO Series from Linx Technologies are Frequency Hopping Digital Data Transceiver Modules that operate from 868 to 900 MHz. These low-cost modules have been designed to minimize the footprint and the number of components required during integration. They can provide an output power of up to 10 dBm and have an Rx Sensitivity of -101 dBm. The modules require a 2 to 3.6 V supply and draw less than 40.5 mA of current in the Tx mode (10 dBm) and 23.5 mA in Rx mode. They have a UART interface and when being used for point-point applications, can be configured once, then send and receive data without the need for further commands.
The module has an FHSS protocol that typically locks in under 30ms at 115 kbps and 60ms at 9.6kbps. This allows it to quickly wake up, send data and go back to sleep, saving power in battery-operated applications that have strict power budgets. It handles all protocol functions automatically.
This module can be used for a wide range of applications including IoT, M2M, Remote Data Transfer, Wireless Sensor Networks and a number of other applications.
Note: In high volume applications, Linx can provide custom firmware to meet the needs of a specific application, removing the firmware design burden.
